Ionic Animations is an open-source utility designed to build highly performant animations by leveraging the Web Animations API, allowing developers to create smooth animations with minimal CPU usage and reduced energy impact. Unlike traditional JavaScript-driven animation libraries, Ionic Animations offloads the animation processing to the browser, which optimizes the animations for smoother performance and better resource management. It provides a straightforward API for creating complex animations, supporting features like grouped animations and gesture animations, and seamlessly falls back to CSS Animations when necessary. Performance tests demonstrate that Ionic Animations consistently achieves high frames per second (FPS) with significantly lower CPU usage compared to leading animation libraries like anime.js, GSAP, and Velocity.js, both on desktop and mobile devices. As part of the upcoming Ionic 5.0 release, the utility is already empowering all animations within the Ionic Framework and invites developers to explore its capabilities and contribute feedback through GitHub.
